Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425436, here are decompositions:
- 43 + 2147425393 = 2147425436
- 103 + 2147425333 = 2147425436
- 127 + 2147425309 = 2147425436
- 139 + 2147425297 = 2147425436
- 193 + 2147425243 = 2147425436
- 199 + 2147425237 = 2147425436
- 223 + 2147425213 = 2147425436
- 313 + 2147425123 = 2147425436
Showing the first eight; more decompositions exist.
